I'm trying to setup audit for our project. I started from the default configuration which works fine.
The next step is to store the user which has made changes. Following the manual I created custom entity revision:
package com.csbi.samples.utils.audit;
import java.io.Serializable;
import java.text.DateFormat;
import java.util.Date;
import org.hibernate.envers.RevisionNumber;
import org.hibernate.envers.RevisionTimestamp;
import org.hibernate.envers.RevisionEntity;
import javax.persistence.Id;
import javax.persistence.GeneratedValue;
import javax.persistence.Entity;
import javax.persistence.Table;
import javax.persistence.Transient;
@Entity
@Table(name="REVISIONS")
@RevisionEntity(CustomRevisionListener.class)
public class CustomRevisionEntity implements Serializable {
private static final long serialVersionUID = -1255842407304508513L;
@Id
@GeneratedValue
@RevisionNumber
private int id;
@RevisionTimestamp
private long timestamp;
private String username;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Transient
public Date getRevisionDate() {
return new Date(timestamp);
}
public long getTimestamp() {
return timestamp;
}
public void setTimestamp(long timestamp) {
this.timestamp = timestamp;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public boolean equals(Object o) {
if(this == o) return true;
if(!(o instanceof CustomRevisionEntity)) return false;
CustomRevisionEntity that = (CustomRevisionEntity) o;
if(id != that.id) return false;
if(timestamp != that.timestamp) return false;
if(timestamp != that.timestamp) return false;
if(username != that.username) return false;
return true;
}
public int hashCode() {
int result;
result = id;
result = 31 * result + (int) (timestamp ^ (timestamp >>> 32));
return result;
}
public String toString() {
return "DefaultRevisionEntity(user = " + username + "id = " + id + ", revisionDate = " + DateFormat.getDateTimeInstance().format(getRevisionDate()) + ")";
}
}
And also custom listener:
package com.csbi.samples.audit;
import org.hibernate.envers.RevisionListener;
public class CustomRevisionListener implements RevisionListener {
public void newRevision(Object revisionEntity) {
CustomRevisionEntity revision = (CustomRevisionEntity) revisionEntity;
revision.setUsername("username"); //for testing
}
}
Here is some lines from log:
DEBUG: org.hibernate.envers.configuration.metadata.AuditMetadataGenerator - Generating first-pass auditing mapping for entity com.csbi.samples.domain.Property.
DEBUG: org.hibernate.envers.configuration.metadata.AuditMetadataGenerator - Generating second-pass auditing mapping for entity com.csbi.samples.domain.Property.
INFO : org.hibernate.cfg.HbmBinder - Mapping class: com.csbi.samples.domain.Property_AUD -> PROPERTIES_AUD
INFO : org.hibernate.cfg.HbmBinder - Mapping class: org.hibernate.envers.DefaultRevisionEntity -> REVINFO
Take a look at the last line of the output.
There is still DefaultRevisionEntity
mapped instead of CustomRevisionEntity
.
I have no idea what is wrong. Any suggestions?
Solved. Entity is not in scanned by Hibernate directory.
